CULTIVATOR.

SPECIFICATION forming part of Lettershlatent No. 290,778, dated December 25, 1883.

Application filed September 5, 1G83. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHN N LAMM, a citizen of the United States, residing at Paola, in the county of Miami and State of Kansas, have invented certain new and useful Improvements in Corn-Cultivators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in cultivators, and has for its object to straddle the rows of corn and to enable the cultivator to go nearer to the fence as well as to lighten the draft on the horses. These objects are attained by the mechanism illustrated in the accompanying drawings, in which- Figure lisa side elevation. Fig. 2isaplan. Fig. 3 is a detail view of the arch, (axletree.)

The letters A Al indicate two elli ptical-shaped plates of metal, separated a short distance apart by intervening blocks of wood, and secured to each other by bolts a.

The letter B represents an arched axle of metal exi ending over the top of the metal plates A A', and securely bolted thereto by the bolts b. The ends of the aXle B carry the wheels E, and the parts R form bearings for the metal pieces D, to which the plow-beams F are pivoted by pivots J. The forward ends of the pieces D have rods f attached to them, and

are supported by the hooks c descending from the plate A. The rods fare provided with hooks at the ends, forming means of attachnient for the horses.

C C are braces which extendfrom the plates A to the arch B.

P is a pole, which is inserted in the open space between the plates A A', and secured to the axle B by a bolt, b', upon which it turns to the right or left a short distance, either way.

F F are plow-beams, the front ends of which enfer slots in the metal pieces D, and are pivoted thereto by the bolts J.

M are metal castings recessed at one end. The recess is to insert the plow-Shanks Q, and

the bolts N penetrate the shank Q, casting M,

and plow-beam F, and secure the whole rmly together. The front ends of the castings are furnished with three holes, through either of which the pin K may be passed, and thus provide means of adjustment of the angle at which the plows L may be set to the plow-beams F F. The pins Kmay be made of such strength that they will break in the event of the plows coming in sudden contact with stones or other obstructions, and thus prevent the breaking of the plow-Shanks Q.

The tongue l? is pivoted to the arched axle B by the bolt b, and, as this construbtion permits it to swing a little to one side or the other, the cultivators may be made to approach more nearly to fences than would otherwise be possible; and I have found by actual practice a great advantage in handling the plow, turning at the end of the field, &c., by this manner of attaching the pole P.

The manner of bitching the horses at the end of each plow-beam by means of the rods f, Ifind to lighten the draft and to be better than when the usual plan of double-trees attached to the pole or otherwise is employed.

I place the plows on beam F on the left side of the row of corn, and the plows on beam F on the right side of the row. This puts the front shovel next the row of corn, and in going through the field it turns all the ground upside down and leaves the middle all turned over and clean.

Having described my invention, what I desire to secure by Letters Patent and to claim is- In a corn-cultivator, the combination of the arched axle'B, the metal plates A A', the pivoted polel), and the wheels E, substantially as shown and described, and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN N. LAMM.
